STOP-MOTION.

SPECIFICATION forming part of Letters Patent No. 595,433, dated December 14, 1897.

Application filed June 4, 1897. Serial No. 639,407. (No model.)

To all whom it'may concern/.i

Be it known that l, JOHN A. BOLEN, of Fall River, in the county of Bristol and State of Massachusetts, vhave invented certain new and useful Improvements in Stop-Motions; and I hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in stop-motions. The class of mechanism to which this stop-motion is particularly applicable is that in which a strand or ber is wound upon a spindle, spool, cop, or similar device.

The object of the invention is' to detect faultywinding, whereby the material is unevenly wound. p

Another object of the invention is to provide an improved stop-motion which shall be brought into operation to stop the machine by the inaction of the lifter-rod of a windingmachine." f

Another object of the invention is to provide a simple and efficient stop-motion for winding-machines.

The invention consists in the belt-shipper, the releasing device therefor, an extension for operating the releasing device, and means connected with the builder mechanism for actuating the extension.

The invention also consists in a stop-motion connected to interrupt the driving device of a, winding-machine and including an actuating member which may be brought into action by the inaction of the lifter-rod.

The invention also consists in the stop-motion in combination with the means whereby itis released for action.

The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described, and pointed out inthe claims.

Figure l represents a front elevation of parts of a winding-machine in the nature of a spooler, showing the stop-motion in connection with the belt-shipper. Fig. 2 represents'a partial end View of the same, partly Fig. 3 represents in end a modied construction for operating the actuating device or pawl-rod. Fig. 4 represents details of the same modification, showing the manner of mounting the levers for the builder mechanism and for the pawl-rods. Figs. 5 and 6 represent detail views 'showing the pawl-rod as applied to the builder-lever of a spinning-machine. Figs. 7 and 8 represent details of the stop-motion rack, its mounting, and the extension-chain connecting the stopmotion belt-shipper-relcasin g device with the racks.

Similar numbers of reference designate corresponding parts throughout.-

In windingmachines the laying of the thread, strand, or fiber is effected .by a

#builder mechanism, so called because by its traverse it causes the material to be Wound in even layers upon the spool, oop, or spindle, the length of each layer depending upon the degree of traverse of the building mechanism.

' The perfect winding of the material is necessary from the fact that the machines through which it passes in the subsequent stages of its manufacture are built to operate upon perfectly-wound material, and that undue building at any portion of the spool or cop prevents the normal response to the action of the succeeding machines. The builder mechanism having a traverse of a length equal to the length of the layers in which the material is to be wound, it is evident that so long as this traverse is maintained perfect winding will result; but for one reason or another--the binding of a lifter-rod at the upper portion of its traverse or the loosening of any one of many bolts-the traverse of the builder is not always accurate, and at such times it is essential that the machine should be stopped, so that the fault may be remedied to prevent the false winding and consei IOO rocal. At one end of the slide is the beltguide 12 and at the other end the lip 13, to which the spring 14 is secured. The opposite end of the spring being secured to the machine-frame, the tension thereon continually tends to move the slide 1l and its beltguide toward the end of the machine and to ship the drive-belt to the loose pulley 9.

Mounted on the rail G is the standard. 15,.

to which is pivoted a bell-crank lever having the arm 1G, with the finger 17, for engaging the lip 13 and holding the slide ll against the strain of the spring 14, and the arm 18, to which the chain 19 is attached, this chain extending for the full length of the machine.

The lifter-rods, as 20, are of the usual construction in the particular machines to which they appertain, and on these rods are adjustably mounted the collars, as 2l. Opposite to each lifter-rod is secured a guide 22, in which a rack-block 23 is vertically reeiprocable, being normally held at its highest point of movelnent by the spring 24, fastened to the block and to a stationary part of the machine. The blocl; has a pin 25, which engages and depresses the chain 19 when the block is moved downward to trip the arm 18 of the bell-crank lever and thus release the spring-operated belt-shipper.

In the different kinds of winding-machines to which this stop motion is adapted the mechanism for traversing the lifter-rods va ries in construction. In one class of machines the builder mechanism acts to alternately raise and lower the series of rods and the devices carried thereby, while in other machines the lifter-rods at both sides of the machine are raised and lowered together. For this reason I have herein shown modifications in t-he manner of mounting the device for engaging and drawing down the rack 23.

Figs. l and 2 illustrate the stop-motion actuator as connected with the building mechanism usually found in spooling-machines, in which the rock-shaft 26, driven in any ordinary manner, is furnished with chain-pulleys, as 27, the chains, as 2S, of which connect with the end portions of builder-levers, as 29, which are mounted to swing on the shaft 30, the lower ends of the lifter-rods 2O resting upon the ends of these levers, but not being secured thereto and traversed by the swinging of the levers. Below the shaft 30 is located the shaft 31, on which the levers 32 are journaled. These levers 32 are connected tothe ends of the builder-levers, as 29, by flexible connections, as 33, whereby the levers 32 are caused to swing in unison with the builder-levers. On the ends of the levers 32 are pivoted the pawl-rods 34, furnished at their upper ends with pivoted pawls 35, having the tooth 3G and the cam-shoulder 37, and being normally supported in an upright position by the fiat spring 38, secured to the pawl and bearing on the pawl-rod. It will now be seen that the rods 2O are lifted by the action of the lever 29 and return to place by force of gravity, being unattached to this lever, while the pawl-rods, being pivoted to the ends of the lever 32, are moved upward and downward by the action ofsaid lever 32. If now from any cause the lifterrod hangs above its lowest point of traverse, the pawl-rod continuing in its downward course, the cam-shoulder 37 rides against the colla-r 21 of the lifter-rod and being thrown inward thereby engages with its tooth 36 the rack 23, drawing the same downward and, through the action of the chain 19, tripping the arm 18 of the bell-crank and releasing the belt-shipper.

In the modification shown in Figs. 3 and 4 the construction and the operation of the lifter-rods, the collars thereon, the lever 29, with its chain-wheel and chain, and also the pawls and their rods are similar to those shown in Figs. 1 and 2. In Figs. 3 and 4 I have, however, shown a modified form of driving for the lever which operates the pawlrods, in which the shaft 30', corresponding to the shaft 30 of Figs. 1 and 2, on which the levers, as 29, swing, is shortened at one end and is secured in the bracket 39 to leave space for the gear 40, fixed on the rotatable shaft 41, to which shaft are also fixed the levers 32. On the shaft 2G, the rock shaft which operates the chain-whee127, is fixed the gear 42, which meshes with and drives the gear 40 to rock the shaft 4l and operate the levers 32 more positively than as shown in Figs. l and 2.

In adapting this stop-motion device for use on spinning-machines the means for operating the pawl-rods are greatly simplified, as will be seen by reference to Figs. 5 and G, which represent portions of a spinning-machine. In this form the lifter-arm 43 is constructed and operated in the well-known manner usual to these machines. This lifterle ver is furnished with the support 44,0n which the lifter-rod 45 rests, the upper ends of a series of these rods supporting the ring-rail 46. Below the ring-rail is adjustably secured on the rod 45 the collar 47, corresponding to the collar 21 of Figs. 1, 2, and 3, and from the end portion of the lifter-arm 43 extends the stud 4S, to which the pawl-rod 34 is pivoted. At the upper end of this pawl-rod is pivoted the pawl 35, furnished with the tooth 36 and the cam 37', and being normally supported in the upright position by the spring 38, as in the constructions previously described. In Fig. G the lifter-rod is broken away for a portion of its length to more clearly show the pawl-rod located back of the lifter-rod in this figure.

The operation of the construction last described is similar to that of the construction shown in the previous figures as relates to the operation of the stop-motion.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a stop-motion of the nature herein IIO described, thecombination with a belt-shipper,'and a releasing mechanism therefor including a movable toothed member, of a pawl for actuating said member, the builder mechanism, and connections between the pawl and the builder mechanism.

2. In a stop-motion of the nature herein described, the combination with a belt-shipper, means for operating the same, and a releasing device for the shipper including a vertically-movable rack, of the builder mechanism, and a pawl operatively connected with the builder mechanism and adapted to be thrown into engagement withthe rack.

3. In a stop-motion of the nature herein described, the combination with the builder mechanism, and a swinging lever, a pawlrod mounted on the lever, and apawl on said rod, of a movable toothed member adapted to be engaged by the pawl, means for engaging the pawl with the member, and a beltshipper-releasing device connected with said toothed member.

4. In a stop-motion, the combination with a beltshipper, reciprocally mounted, and

Vshipper having an upwardly-extending lip,
